iBe it known t fat 1I, `fR-ANsoM Coox, of

`Saratoga Springs, `county ofSara'toga, and

State of New York, have invented afnew; =,and @useful machine for producing a -blast of wind oriai'r to be iu'sedinfheating, smelt ling, f and 'other `mechanical fandfma-nufacturf `ing purposesfwhich WIfdenomina a hyfv Cdraulic blow-inglmachine,"j `and I ydo here-j and exact description ao'f ithe `coiistruction Figure 1, `is r'a :sectional elevation ofthe machine as suspended` in `the cistern, in`

which A represents the cistern; O, the shaft, of the wheel; B, the spokes; C C C, the felly or rim; E E E, the air boxes; D, the cam; J J J, the guiding cranks of the air boxes; K K K, the throwing cranks of the air boxes; T T T, the discharging mouths of the air boxes; G, the catch block for throwing forward the crank J g-H, `the receiver.

Fig. 2 is the cam in which M M represents the groove or channel in which the guiding cranks of the air boxes move.V

Fig. 3 is a view of the receiver and one of the air boxes. In the latter the discharging mouth T '1s more distinctly shown, and the part U U, which partly closes the open side of theair box is exhibited.

Fig. 4, is asectional view of the wheels showing the dish or concavity of one of them at X X.

To construct this blowing machine, two wheels, or disks, or two sets of arms or spokes, all of which may be made of wood or iron, should be secured to a shaft at such distance from each other as will enable the `builder to insert air boxes between them of the capacity required. The sides of these wheels or arms, or one of them, should be dished near the ends of the arms or periphery of the wheel with the concave side outward as shown in Fig. 4. Where wood is the material used, an overhanging projection may be built on the periphery of the disk or wheels so as to form a concavity or recess in the side of the wheel, to enable the receiver to project over the mouths of the air boxes to receive their discharge of compressed air.

The air boxes may be made of such material as ,suits the builder, having their open side partly closed by the piece U U, as

shown in Fig. 3, ileaving fthe mouth T, as

exhibited in "the `same figure. These "air boxes are then to bep placed between 'the kwheels or disks on the'Shaft-,with theiriends securedvto said iwheels near 'their lperiphery by movable joints or journals and at such distance *from each otherlas will allow `them a free rotary movementontheir own journals. To each of these ijournals cranks are 4attached, or Aformedof 'the same piece 'with the journal. The longer cranks, J, U, U, whichI denominate the guiding cranks, `are bent withw'a handle lat one'end. This han- "dl'e, l.with or withoutia `friction roller, moves lin the icam igroove M M. This crank and cam groove `guide lthe air boxes `through most of their revolution, determining the position in which they shall enter the water, empty their compressed air into the receiver and emerge. from the water. cranks, K K Ke at the .other ends of the air boxes, stand in an opposite direction from the long cranks and serve by coming in contact with the block G, to turn the air box and thus throw forward the long crank J, so that it again enters the cam channel M, and gives the air box such a position that it leaves the water with ease.

The receiver H, built of wood or iron and strengthened by bolts, is then suspended in the cistern or flume by the side of the wheel with its lower and open end projecting into the dish or recess of the wheel. before mentioned and over the mouths ofthe air boxes marked T. Thecam D is fully described by the drawing of it.

To put this machine in operation the flume or cistern in which it is suspended is nearly filled with water so as to immerse al- Inostone half of the wheel. The wheel is then slowly turned by any power which may be preferred, in the direction which would carry the long crank under D, in Fig. 1, to the point of the cam at the left. The cam groove M M, and the cranks J J J, cause the air-.boxes E E E, to enter the water with their open sides downward. As they are forced downward in the water, the air within them is increasingly compressed until they reach the receiver H, when the `cam and.

The short which by turning the air box throws forward the long crank J, so that it again enters the cam channel M. As the air boxes ascend the cam and crank hold them in such a position that the water is poured from any part of the receiver above water.

The receiver having its lower end open and mostly immersed, the pressure of the water from below serves to keep the discharge of the blast steady and even. 'Ihe depth to which the lower end of the receiver extends in the water determines thepressure which may be obtained in the blast. Pipes for leading off the blast may be inserted in any part of the receiver above water.

What I claim as my invention and which I desire to secure by Letters Patent is l. The use and application of boxes, tubs or cavities, attached to wheels, disks or arms by movable joints or journals and then carried in a rotary direction alternately through air and water; said boxes or cavities moving at the same time on their own journals in such a manner that they shall enter the water with their open sides downward and when beneath the same. shall empty or discharge the air which has been compressed within them by the water, into a receiver which is separate from such wheels and air boxes; all for the purpose of producing a-blast of air to be used in heating, smelting and other mechanical operations.

2. I also claim for this purpose the dish, recess or concavity of the wheel so as to allow the receiver to projectl .over the mouths of the air boxes to receive their compressed air. Y

3. I also claim for the same purpose the cam D, the cranks J J J and the cranksK K K, attached tothe air boxes, together with the piece U U, on the open side of the boxes, the mouth T, for discharging their compressed air and the block Gr, for throwing forward the cranks J J J.
